Question

A person purchased a slot machine and tested it by playing it 1 comma 291 times. There are 10 different categories of? outcomes, including no? win, win? jackpot, win with three? bells, and so on. When testing the claim that the observed outcomes agree with the expected? frequencies, the author obtained a test statistic of chi squaredequals 8.374. Use a 0.10 significance level to test the claim that the actual outcomes agree with the expected frequencies. Does the slot machine appear to be functioning as? expected?

Test Statistic:

Critical Value:

P Value:

Explanation / Answer

Test statistic = 8.374

Critical value = 16.9190

Since chi square Cal < critical value, we donot reject null hypothesis.

P value = 0.4969 at df =9 with Alfa =0.10

Since p value > 0.10 we donot reject Null hypothesis.

In both conditions we can conclude that the slot machine appear to be functioning as expected.
